    It's a whirlpool, same as KitchenAid or others. Scotsman tech support should have the ohm readings. Just say it's a Scotsman and they will help.

    You could use an evaporator control or delay timer with the Scotsman CM

    The low side pressure is a bit low at the start. I would expect 300/60 at the start though 270/30 sounds very normal at the end. What are the defrost pressures?

    High gear motor amps often disappear with a good acid wash. Follett has an
    excellent help line at 1-800-523-9361. If you get a chance their service school
    is very good also.

    A much easier solution would be to buy the Hoshizaki IM series ice machine which is a Kold-Draft clone. This model is available, last I heard, in Asia and Europe but not North America.

    A good example of the death of a Cornelius by evaporator separation. The evaporator looks to me like a typical six year old Cornelius. Thank goodness they're almost all gone now.
